easypackages: Easy Loading and Installing of Packages

Version 0.1.0

Easily load and install multiple packages from different sources,
including CRAN and GitHub. The libraries function allows you to load or attach
multiple packages in the same function call. The packages function will load one
or more packages, and install any packages that are not installed on your system
(after prompting you). Also included is a from_import function that allows you
to import specific functions from a package into the global environment.
